Usually when a player really hates a game and rage quits the publisher and developer just lose a gamer for future titles they release. If it’s a subscription-based game then it’s a more serious loss of revenue. But one player in Japan didn’t just rage quit, he sold millions of shares in the game’s publisher causing a drop in the value of its stock.

The player made the following post on October 2nd after what must have been a really infuriating session with the game:

First thing in the morning tomorrow, I intend to instruct those who manage my precious Square Enix stock (however little it may be) to arrange to sell all of it. To Square, thank you for the enjoyment of your products up until now, with the exception of this last one. Goodbye.

Such comments are a common site on forums from upset gamers, but this gamer was quite important to Square Enix. It turns out he owned 1% of the company’s stock, which equates to $26 million worth. He went through with the sale too, which saw the value of the stock fall from 1800 yen to 1735 yen–a major drop in value for the company.

The message to Square Enix is pretty clear: Some of its most loyal gamers also own millions in company stock so don’t make a crap game or else.

For anyone in the West holding on to millions in Square Enix stock options, you should be well into your first month of playing the game now. Is a rage quit share sale on the cards for any of you?
